## Discrepancy

ENGINE WILL ROTATE WITH STARTER BUT WILL NOT START.  ACFT ENGINE REPLACED WITH ENGINE IAW STC SA-703-GL, ENGINE O/H WITH NEW MAGNETO'S AND HAS NOW ACCUMULATED 32.7 HS.  FOUND THE LT MAGNETO CONDENSOR FAILED.  THIS ENGINE MODIFIED BY STC TO START ON LT MAGNETO ONLY, WITH THE LT MAGNETO CONDENSOR FAILURE THE LT MAGNETO WAS INOPERATIVE.  REPLACED THE LT MAGNETO CONDENSOR PN M-3984, REASSEMBLED MAGNETO AND REINSTALLED.  SUBSIQUENT OPS SATISFACTORY.
